Rain on Vancouver Island will ramp up today thanks to a stream of moisture aimed directly at the South Coast of B.C.

This stream of moisture is called an atmospheric river. Essentially, it’s a column of condensed water vapour in the atmosphere that produces heavy rain as it moves inland. And that’s exactly what we’re going to get over the next few days as two fall storms approach in quick succession.

Storm #1: Tonight through Tuesday

Rainfall warnings are in effect for West Vancouver Island and North Vancouver Island, warning that up to 100 millimetres is expected to fall by Tuesday morning.

Howe Sound is also under a rainfall warning, expecting 50-70 millimetres of rain in the same time period.
